Definitions

  • the present invention relates to an apparatus and a method for disposing empty wasted cans such as beer cans, fruit juice cans or the like by pressing these cans.
  • the present inventor has proposed, in the specification of Japanese Patent Application No. 2-283657, a wasted can disposal apparatus which presses, between a movable press member and a stationary press member, wasted and which are received by a bottom plate.
  • Figs. 11 to 14 of Japanese Patent Application No. 2-283657 cans 4' put into the space between a stationary press member and a movable press member are received by a bottom plate 50' which is set at a level below the lower ends of both press members. and are pressed between these press members as the movable press member is moved towards the stationary press member, as shown in Figs. 13 to 16 attached hereto.
  • numeral 5' denotes a motor
  • 26' denotes a press member
  • 29' denotes a transmission member
  • 30' denotes an elastic member
  • 50a' denotes a bent portion
  • 51' denotes a motor
  • 52' denotes a shaft.
  • the can 4' when pressed by the apparatus, is deformed not only in the direction of compression but also in the vertical direction perpendicular to the direction of pressing, so as to push the bottom plate 50' downward, thus swelling out downward beyond the lower ends of the pressing members.
  • the portion of the can swelled out from the region between both pressing members is no more pressed, so that a non-pressed portion undesirably remains in the can after the press work.
  • an object of the present invention is to overcome the above-described problems of the prior art.
  • the present invention provides a can disposal apparatus and method in which a support plate for receiving and supporting cans is initially set at a level above the lower ends of first and second press members and is moved to down to a level below the lower ends of the press members at least during the pressing.
  • the wasted cans put into the gap between both press members are supported by the support plate and, when the pressing is commenced, the support plate is retracted to the level below the lower ends of the press members. Consequently, any vertically swelled portion of each can is still within the region between the first and second press members so that the amount of swelling of the can out of the pressing region is reduced or substantially eliminated.
  • the support plate undesirably tends to move into a space behind the moving press portion, due to the arrangement that the supporting portion of the support member is positioned above the level of the lower ends of the first and second press portions. This, however, does not take place actually because, in the present invention, the side tabs of the support plate engage with the guide portions in accordance with the operation of the advancing/retracting means, so as to downward rotate the support plate to a level below the level of the lower ends of the first and second press portions.
  • a can disposal apparatus as an embodiment of the present invention is generally denoted by 1.
  • the apparatus 1 has a first press portion 2 and a second press portion 3 between which a can 4 to be disposed is placed.
  • the second press portion i drivingly connected to a motor 5 through a mechanism for converting a rotational motion into a linear reciprocating motion, so that the second press portion 3 is moved towards the first press portion 2 so as to press the can 4 therebetween.
  • the apparatus has a guide section A which decides whether the can 4 put into the apparatus is to be guided to a pressing chamber or to a non-pressing chamber, and a press section B for pressing the can 4 which has been introduced into the pressing chamber.
  • the guide portion A includes a door 7 rotatable about a pivot shaft 6, a stopper portion 8 which decides whether the weight of the can 4 put into the apparatus is grater than a predetermined weight, a releasing portion for releasing the stopper portion, and a guide 10 for selectively guiding the can 4 either to a passage B1 leading to the pressing chamber and a passage B2 leading to the non-pressing chamber.
  • a sensor 11 disposed in the vicinity of the door 7 is capable of sensing the state of the door 7, and delivers a signal to a controller 12 when the door has been moved from the open position to the close position.
  • the stopper portion 8 includes a lever 81 having an L-shaped sectional shape, pivotally supported by a pivot shaft 13.
  • a spring 14 is retained at its one end by the lever 81 and at its other end by a protruding portion provided on an activating member 20.
  • the arrangement is such that, when the weight of the can 4 exceeds a predetermined value, the spring 14 is compressed to allow the stopper portion 8 to rotate counterclockwise, so that the lever 81 interrupts the passage of light from a photoelectric tube 15.
  • a signal is delivered to the controller 12 when the light is interrupted.
  • the releasing portion 9 is for releasing the can 4 from the stopper.
  • the releasing portion 9 includes a first solenoid 16 cooperating with a first plunger 17 to which is secured a first arm 18.
  • the aforesaid first activating member 20 is pivotally connected to the other end of the first arm 18.
  • the guide 10 is adapted for selectively guiding the can 4 either to the aforementioned passage B1 leading to the pressing chamber and the aforementioned passage B2 leading to the non-pressing chamber.
  • the guide 10 includes a second solenoid 21 cooperating with a second plunger 22 to which is secured a second arm 23.
  • a guide member 25 is pivotally connected to the other end of the second arm 23 by means of a pivot shaft 24.
  • both the first and second solenoids 16 and 21 are shown in de-energized state, i.e., OFF state.
  • the pressing section B which is composed of the first and second press portions 2,3 and the support plate 70, clamp the can 4 which has been put into the gap between both press portions 2 and 3 through the guide 10 held in open state.
  • the rotation output of the motor is converted into linear motion of the second press portion 3 so that the second press portion 3 is moved towards the first press portion 2 so as to pres the can 4 and then moved away from the first press portion 2.
  • the mechanism for converting the rotary motion of the motor shaft into linear reciprocating motion includes, as shown in Fig. 12, a roller 52' which is pressed into a channel 32' formed between a pair of transmission members 29' and 29''.
  • the apparatus also includes a first connecting rod 82 contacting a cam 81, a second connecting rod 83 connected to the first connecting rod 82, a third connecting rod 84 connected to the second connecting rod 83, and a fourth connecting rod 87 connected to the support plate 70 and having a projection 86 engaging with an elongated hole in the third connecting rod 84.
  • These connecting rods are omitted from Fig. 12.
  • An expandable elastic member 30 enables the transmission members 29', 29'' to move as a unit together with the second press portion 3, when the force acting on the pressing surface of the second press portion 3 is below a predetermined level, e.g., 250 kg.
  • the support plate 70 is placed at the lower end portion of the press apparatus so as to receive the can 4 which has been put into the gap between both press portions 2 and 3 as shown in Fig. 3.
  • the support plate 70 is adapted to be retracted at least during discharging of the pressed can, so that the pressed can drops into a collecting box 53.
  • a sorting guide 55 is adapted for sorting the pressed cans according to the materials of the can, so that iron or steel cans are introduced into the collecting box 53, while aluminum cans are introduced into another collecting box which is not shown.
  • the support plate 70 has two portions which are hinged to each other through a hinge 71 and are urged by a resilient member such as a spring 72.
  • the bottom portion of the support plate 70 has slits 73 which divide the bottom portion into a central supporting portion 70a for supporting the can and the remainder wing portions 70b.
  • the supporting portion 70a has been slightly bent upward so as to be positioned above the level of the wing portions 70b. Lateral ends of both wing portion 70b are bent upward to provide side tabs 74.
  • the support plate 70 is divided into a stationary part and a movable part which are hinged together through the hinge 71 urged by the resilient member 72, and the movable part has sits 73 which define the central supporting portion 70a and the remainder both wing portions 70b, the supporting portion 70a being slightly bent upward so as to be positioned at a level slightly above the level of the remainder portions 70b.
  • the support plate 70 is associated with a advancing/retracting means 80 which is adapted to advance and retract the support plate 70.
  • the advancing/retracting means 80 includes, for example, a cam 81 driven by the motor 5, the first connecting rod 82 contacting the cam 81, the second connecting rod 83 connected to the first connecting rod 82, the third connecting rod 84 connected to the second connecting rod 83, and the fourth connecting rod 87 connected to the support plate 70 and having the projection 86 engaging with the elongated hole 85 in the third connecting rod 84, all of which are mentioned before.
  • the first connecting rod 82 is urged by a spring 88 so as to be held in contact with the cam 81, and the fourth connecting rod 87 is connected to the support plate 70.
  • a spring 88 is used for urging the end of the first connecting rod 82 into contact with the cam 81, such a spring 88 may be substituted by a spring 88' which is provided on an attaching plate 87' integrally secured to the fourth connecting rod 87 as shown in Figs. 10 and 11.
  • Numeral 89 denotes a guide of the fourth connecting rod 87 provided on a bottom plate 89'.
  • a guide portion 90 provided at lateral sides of the pressing chamber C are adapted to contact with the side tabs 74 of the support plate 70 in accordance with the operation of the advancing/retracting means 80, so as to swing the support plate 74 downward away from the bottom ends of the first and second press portions 2 and 3 against the force of the spring 72.
  • the supporting portion 70a of the support plate 70 is held at a level above the lower ends of the first and second press portions 2, 3, so as to support the can 4. The pressing operation is commenced in this state.
  • the distance between the first and second press portions 2 and 3 is maximized as shown in Fig. 2, and the end of the first connecting rod 82 is held in contact with the valley portion of the cam 81, while the support plate 70 has been fully advanced.
  • the cam 81 rotates in the direction of an arrow shown in Fig. 2, so that the second press portion 3 is moved towards the first press portion 2 thereby pressing the can 4 therebetween.
  • the pressed can is swelled downward so as to push downward the supporting portion 70a of the support plate 70, so that the supporting portion 70a is lowered to a level below the lower ends of both press portions 2 and 3.
  • the support plate 70 is removed from the region under the lower ends of the first and second press portions 2 and 3.
  • the second press portion 3 is moved towards the first press portion 2, while the end of the connecting rod 82 is moved from the valley to the crest portion of the cam 81, whereby the support plate 70 starts to move backward, as shown in Figs. 4 and 5.
  • the support plate 70 is reset so as to position the supporting portion 70a at a level above the level of the lower ends of the first and second press portions 2 and 3, thus preparing for the receipt of the next can.
  • the support pate 70 is prevented from entering the space behind the moving press member which is, in this case, the second press portion 3.
  • the retraction of the support plate 70 is commenced immediately after the start of the pressing.
  • This is only illustrative and the arrangement may be such that the retraction of the support plate is commenced when the pressing is being performed. It is even possible to retract the support plate 70 after the completion of the pressing.
  • Such change of the timing of commencement of the retraction can be freely set by altering the rotational phase or contour of the cam 81.
  • the support plate 70 has been removed from the region beneath the lower ends of the first and second press portions 2, 3 so as not to hamper the discharge of the pressed can.
  • one form of the can disposal method of the invention for disposing a wasted can comprises: a first step of placing the wasted can into a gap formed between a first press portion and a second press portion such that the can is supported by a supporting portion of a support plate, the supporting portion being positioned at a level above the level of the lower ends of the first and second press portions; a second step for commencing a relative movement between the first and second press portions toward each other so as to start pressing the can, while moving the supporting portion of the support plate to a region below the lower ends of the first and second press portions; a third step for further continuing the relative movement between the first and second press portions so as to further press the can, and then removing the support plate from the region under the lower ends of the first and second press portions during the pressing of the can; a fourth step for causing a relative movement between the first and second press members away from each other so as to release and discharge the pressed can; and resetting the support plate such that the supporting portion is positioned between the mutually spaced apart first and second
  • Another form of the method for disposing a wasted can comprises: a first step of placing the wasted can into a gap formed between a first press portion and a second press portion such that the can is supported by a supporting portion of a support plate, the supporting portion being positioned at a level above the level of the lower ends of the first and second press portions; a second step for commencing a relative movement between the first and second press portions toward each other so as to start pressing the can, while moving the supporting portion of the support plate to a region below the lower ends of the first and second press portions; a third step for further continuing the relative movement between the first and second press portions so as to further press the can; a fourth step for removing the support plate from the region under the lower ends of the first and second press portions during the pressing of the can, and causing a relative movement between the first and second press members away from each other so as to release and discharge the pressed can; and resetting the support plate such that the supporting portion is positioned between the mutually spaced apart first and second press portions at a level above the
  • both the second press portion 3 and the cam 81 are activated by the same motor 5, without requiring any sensor or the like for the purpose of control. Consequently, the control system is simplified and the operation speed can be increased.
  • the present invention offers the following advantages.
  • the supporting portion of the support plate for supporting the can is positioned at a level above the lower ends of the first and second press portions when the pressing stroke is commenced, the lower end of the can is still held within the region between both press portions, despite any downward swelling of the can occurring during the pressing, so that swelling of the can material out of the lower ends of the press portions can be minimized, thus reducing non-pressed portion of the can which tends to appear in the conventional can disposal apparatus.
  • the support plate undesirably tends to move into a space behind the moving press portion, due to the arrangement that the supporting portion of the support member is positioned above the level of the lower ends of the first and second press portions. This, however, does not take place actually because, in the present invention, the side tabs of the support plate engage with the guide portions in accordance with the operation of the advancing/retracting means, so as to downward rotate the support plate to a level below the level of the lower ends of the first and second press portions.
  • the spring associated with the second press portion which normally moves together with the second press portion without contracting, is compressed when a load exceeding a predetermined level, so as to protect the driving system for driving the moving side of the apparatus, in particular the driving motor, against any overload.
  • the method of the present invention has the first step in which the can put into the space between the first and second press portions is supported by the supporting portion of the support plate, the supporting portion being set at a level above the lower ends of the first and second press portions, and the fourth step in which the support plate is retracted from the region beneath the lower ends of the first and second press portions at least when the pressed can is discharged. It is therefore possible to minimize any non-pressed portion of the can which tends to remain after the pressing operation.
